Suspense novelist Gu Yebai has a perfect marriage that is envied by the world. Her husband Lu Jingshen is a top lawyer, rational and rigorous, and treats her with the utmost gentleness. Every step of their love is like a carefully written script by fate, full of soul-resonating coincidences.
Until the anniversary, Gu Yebai gave him a shocking gift - a straw ring that was exactly the same as Lu Jingshen's childhood dream. While marveling at this, Lu Jingshen discovered a photo of the late talented painter Shen Zhishi among her dusty old things: the young man had an identical grass ring on his finger.
The perfect world suddenly cracked open. Lu Jingshen began to examine his life like a detective, and was horrified to discover that all their "unique" sweetness, from the coffee shop where they met to their daily habits, were actually exact replicas of Gu Yebai's past relationships.
When the evidence was conclusive, Lu Jingshen questioned her, but Gu Yebai gave a more heartbreaking explanation: all this stemmed from her mental illness that was unable to face the trauma. Should you choose to believe this pathological lie full of love, or uncover the truth that may be even more embarrassing? Can the real temperature of a relationship that started out as fiction still be measured?
